PAPER FILE AND BINDER..

Application filed December 10,v 1920.

is a specification.

This invention has as its main object to provide a portable file inwhich perforate sheets of paper may be neatly and compactly preserved incondition for ready reference.

Another object is to provide means whereby the file prongs may besecurely clamped when in an engaged position, but which permits easy andrapid insertion or removal of individual papers.

A further object is to provide means facilitating the transference ofany desired portion of the papers en bloc, and without disarrangement ofthose remaining.

A still further object is to provide means `for clamping the papers onthe file prongs.

These and other analogous objects are attained. by the novelconstruction, combination and arrangement of parts hereinafter describedand shown in the accompanying drawings, forming an essential part ofthis disclosure, and in which Figure 1 is a perspective view showing thefile and binder extended, the engaging prong elements being clamped,and` indicatingin broken lines the transfer device in operativeposition.

Figure 2 is a similar view of the same, exhibiting the purpose of theinvention.

Figure 3 is a fragmentary sectional view taken on line 3-8 of Fig. 1,and drawn to an enlarged scale.

Figure 4 is a plan view of the parts shown in Figure 8.

Figure 5 is a sectional view taken on line 5*5 of Figure 3.

Figure 6 is a fragmentary sectional view taken on line 6-6 of Figure 1.

Figure 7 is a fragmentary side view of the engaged ends of the file andtransfer prongs, drawn to a further enlarged scale.

Figure 8 is a plan view of the clamp used to hold papers on the fileprongs.

Referring to the drawings in detail, the numeral 10 designates a pair ofsti cover plates preferably made of heavy paste-board and covered withflexible textile fabric, this Specification of Letters Patent.

retreated .nay is, ieee. Serial No. 429,620.

fabric actingas hinges at the folding lines 11, which connect with thecentral element or backing plate 12, similar in construction to theplates 10.

Secured centrally of the center plate, upon its inner side, by rivets14, is a thin metallic plate 15, bent at right angles outward along its'edges forming uprights 16 and 17, the latter of which is extended androlled into a cylindrical bead 18 enclosing a rod 19 in the manner of ahinge.

` The extending elements of the' rod 19 are bent to present a pair ofarcuate parallel curves, constituting the Vtiling prongs 20 terininatingin straight ends 21 containing central drilled openings 22.

\ Formed in the edge of the opposite upright 16 are a pair of recesses,or slots 23 receptive of the prong yends 21 when turned downward toenter the same.

An elongated spring plate 25 is held by rivets`26 to the outer sideofthe upright 16, the plate having curved ends kand offset portions 27adjacent the rivets.

Interposed between the spring plate and upright is a slide`28 having acentral longitudinal slot 29, the length of the-slot being in excessofthe distance between the rivets 27 which pass through it. The extremeends ofthe slide 28 are bent forward forming stops 30 and 31 adapted tomake contact with the ends of the upright 16 thereby lim-4 e iting themovement of the slide.

The upper edge of theslide is bent outwardly and then curved reentrantlyforming an'open U shaped guard 32its upper edge being in register withthe top edge of the upright 16, and in which are received the ends 21 ofthe file prongs, the `same passing through slots 33 intheupper portionof the guard when the slide is pushed so that the stop 30 makes contactwith the end of thev upright, and when the guard and slide are moved totheir other eXtreme position, the ends 21 are securely locked in theguard, and it is to be noted that the slide is frictionally vheld ineither position, due to the spring plate 25. Y

The foregoing structure constitutes the simpler form of file and, aswill be seen, is effective for its purpose, thesheets or leaves of paperor other material to be filed, having been perforated, are placed inposition upon the connected file elements 20, which are then turneddownward, through the slots B3, into the recesses 23 and the slide movedto engage their ends in a manner easily understood.

ln order to shift any considerable number ot papers from the file in apack the Jfollowing` additional device is used.

Secured on the inner side of the cover plate adjacent the lockingdevice, is a metallic plate 35, held by rivets 36 and having its outerelge rolled into a bead 37 loosely containing a wire or rod 38, bent top-resent substantially straight parallel fork elements 39 turnedoutwardly at their ends and reduced in diameter, presenting pin-like eX-tremities 40 adapted to be received within the openings 22 of the prongswhen brought into engagement, as best shown in Figs. 2 and 7, a coiledspring 4:1 encircling the rod 38 and operatively engaging one oi' the'fork elements 39 and plate l0, acting to press the pins or spurs 40into the ends 21 and maintain them in engagement.

lVhen these elements are not required, one of the rods is engaged belowa clip 42, held by a rivet L13 to the cover plate, near the end of therod, which, as will be understood, is sufficiently resilient to permitspringing inward from below the clip when desired.

1n order to hold the loose papers compactly on the iile prongs, as shownat the right ot Fig. 2, the clamping device disclosed in Fig. 8 is used.

This device is comprised of a loose metal plate 45, having a beaded edge46 and containing openings 47, the material removed from the openingsbeing formed into rolls a8 used as bearings for a rod 49 bent into acentral loop 50 between the bearings to be used as a handle, the ends otthe rod being turned in the same plane as the loop, forining fingers l.i

Circular openings 52 are formed through the plate, the saniebeingreceptive of the iile prongc 2O whenthe plate 45 is pressed thereoverand the elements 51 turned out-` ward, away from the openings 52 byproperly manipulating the handle 50.

Vvlhen the plate has been pressed into position on the paper, the`handle is turned as shown, the fingers 51 forcing the prongs outwart',causing them to bind in the openings and clamp the papers firmly inposition.

From the foregoing it will be seen that a neat appearing and effectiveiile and binder has been disclosed capable of fulfilling its purposesand that the same is of simple and inexpensive construction.

Having thus described my invention and set forth the manner ot itsconstruction and said prongs, said rod being use, what l claim as newand desire to secure by Letters Patent, is

l. A lile comprising a plate, uprights formed at the lateral edges ofsaid plate, apair of arcuate prongs, a rod integral with hinged in oneof the uprights, the other upright having recesses receptive of the endsoi' said prongs, a slide movable on the outer side ot' the last namedupright, a locking means formed with said slide into which the prongends enter, stops for said slide and means for resiliently holding saidslide on the upright.

2. A File comprising a pair ot covers, a backing plate hingedly engagedtherebetween, a metal plate fixed on said backing plate, uprights'formed with the lateral-edges of said metal plate, a pair or' prongshinged in one ot said uprights, means on the other upright ior securingthe ends of said prongs when entered therein, a forli hinged to one orsaid covers, outturned spurs at the ends of said forli, said spurs beingengageable in openings in the ends of said prongs and a spring adaptedto cause such engagement.

3. A lile comprising a pair of covers, a backing plate hingedly engagedtherebetween, uprights on said plate, a pair of curved prongs hinged toone of said uprights, said prongs having longitudinal openings at theirfree extremities means on the other of said uprights for engaging ordisengaging said prongs, a fork hinged to the cover adjacent the lastnamed upright, said jrorlr having parallel elements terminating in spursturned at an angle, said spurs being engageable in the mentionedopenings in said prongs, a spring arranged to force said spurs towardssaid prongs and a clip on said cover whereby said fork may be retainedthereagainst.

A. file comprising a pair of rigid covers, a rigid backingI plat-ehingedly connecting said covers, uprights extending in parallel fromsaid plate, one of said uprights having a rolled edge, tile prongspi'voted in said edge adapted to extend over the other upright and enterrecesses therein, a guard receptive of the ends or said prongs slidablymounted on the last named upright, stops limiting the action of saidguard, spring means Jfor lrictionally holding said guard in adjustment,a fork pivoted on one of the covers, means co-operative between saidfork and prongs whereby they are adapted to form continuous guides forarticles disposed thereon and a clip for holding said fork when not inuse.

In testimony whereof l have signed my name to this specification.

HARRY BRUNDAGE.
